`i Application filed September 27, 191.9. Serial No. 336.708.

i '0 ctt te flour/t fntaje/ conce/Mt lle it known that Ldoi-IN lnwlinn`Porn- 'roi:, a suhject of the hang of Great Brit- :iin and ireland,residing at Brackley, Park lh'escent, lieterhorough, 1n the county ofNorthants, England, have invented certain new and usefulimprovements"Relatingto Dough-Molding Machines, of which the followingis" a specification. o

lThis invention relates to dough molding machines of the 'type withwhich the inoldinn; is ell'ected h v the coiflingof the dough portionslov the action *of a rotating` spindle.

The object of the invention is to provide a simple and convenientmolding' machine et the said tvne capable of simultaneoushT receivinc.`and operating` upon a series of dough portions `innnediately on theirdischarge 'from a dividing; or other machine, and delivering` the same,after molding, directly on to conveyor trays which may form part of adough proving apparatus.

lteterrinp; to the four accompanying sheets of explanatory drawing.

`litigare 'l is a side elevation, Fin: E2 a plan (with hinged top coverremoved), and llig. Il an end elevation of one form of a two spindlemachine constructed in iweordance with this invention.

Fig. tis a side elevation and lfigr. 5 an ond elevation of another typeof such inaNr chine.

rl `he saine reference letters in the ditlicr ent views indicate thesaine or similar parts.`

ll.eiferring` to the machine illustrated hy lilas. l, 2 and 3. the doughportions `from Llli titi

the dividing machine pass down the guide chutes or troughs as a (shownat liin's. i and Q) on to the upper part oi' the endless hand 7) (whichterms the hase of the troughs) and in a suitahle position thereon to heengaged hy' the spindles c and coiled or wound around the saine. rlheendless hand F) is mounted upon the pulleys /Z which are free to rotate.and thus as the dough is gradually drawn toward the spindles hy thewinding action of the latter the hand t can travelavith it, soavoiding,1 any drag upon the dough such as would Voccur with a lined orstationary supporting' surface. By the operation of the rotating'spindles c the dough lumps or portions are wound or rolled into coilsupon the said spindles. To provide for the increasingdiameter or growthof the` rolls or coils as the dough portions are thus operated upon bythe spindles c the hand and its supporting` pulleys d are mounted at oneend of a sliding' frame c which 1s pivote'd .at 7 and has counterweightsg. The said counter-weights g serve to keep the dough pressed upward ortoward .the spindles while permitting of the depression oi the hand toaccommodate the increasinni diameter or growth of the dough coils. i

The ceiling spindles c are rotated tl'irough the mediunicof the skewwheels it on` the first motion or` driving1 shaft t' which enor are `1n@fear with the skew pinions 7. on the spline shafts 7u forming` part of4or in attachment with the ceiling; spindles c.

'lhe sliding; movements ofthe spline shafts 7: to effect the withdrawalof the spindles c from the completely coiled updoughpieces and thesubsequent return of the spindles aforesaidj is obtained by means of agrooved cam l onthe shaft m, the latter being rotated from. theaforesaid drive shaft z' through the gear wheels n, 0, p, g. The cani Zengagesthe lever r of the rock shaft s and as such lever. with itsfellow r is connected to the hridgre like member which engages collarsif, fixed on the spline shafts lit, the action of the cam gives therequired reciprocatory or sliding;` moven'ients of the spline shafts andthe ceilingspindles c.

@n the said shaft 'in there is also a cani vv which engages a lever wloosely mounted on the fulcrum shaft s to which the aforesaid levers frand r are tired. finch lever so is linked to the lever /i which with itsfellow 1/ is secured to theV rock shaft rlhe lower ends of such leversy/ and 37 are linked or connected with the aforesaid pivotal slid? lill)the machine and for desceinlinnr on to the Mld llllll veoiling spindlesc.

is dispensed with and in place of same a pair of rolls as l and 2 arearranged in association with each winding or eoiling spindle c. For eachsuch pair of rolls a supporting arm as 3 is employed, each arm beingpivotally mounted at its upper end on a spindle 4. The spindles'l areconnected by chain gearing and are positively rotated by a chain drivefrom. one of the From such spindles 4 the respective pairs of rollsaforesaid are positively rotated by driving chains. Projections as 3from the arms 3 abut against lateral .engaging pins Vas 5 from the link6 connecting the levers 7 and 8 which are rocked .by the action of a camin association with the spring 9. By such rocking the arms 3, with rollsl andQ, are swung aside to permit of the descent of the coiled up doughpieces, (after the withdrawal of the coiling spindles atherefrom) intothe shelves as 10 of a dough prever.V The springs as 1l r serve to drawthe rolls l and 2 toward the ceiling spindles c while providing for thegrowth or increasing diameter of the coils during the windingor ceilingoperation.

'Having thus described my invention what I claim as new and desire tosecure by Letters Patent is l. Machines for the coiling of lumps orunshaped portions of dough without prior sheeting or stretching of thesaine, eomprising ceiling spindles, chutes through which the said doughlumps fall freely into engagement with the said spindles, means formaintaining the said engagement; during the coiling operation, and meansfor withdrawing the spindles from the dough, as set forth.

2. Machines for the simultaneous eoiling of' a series of lumps ornnshaped portions of dough without prior sheeting or stretching of thesame, comprising a series of coiling spindles, chutes through which thesaid dough lumps fall freely into engage l ment with the said spindles,means for maintaining the said engagement during the coiling operation,and means for the simultaneous reciprocation of all the spindles, as setforth.

In testimony whereof I have signed my name to this specification.

JOHN EDWARD POINTON.
